Abstract

An electrical connection system comprises a female connector having a plurality of female terminals, and a male connector having a plurality of male blade terminals having projecting portions that plug into the plurality of female terminals respectively when the female connector and the male connector are mated. The male blade terminals are staggered having a first population with their tips at a first relative position and a second population with their at a second different relative position so that the first tips and the second tips do not touch and fully engage the mating female terminals and the plurality of male blade terminals at the same time thereby lowering the peak engagement force required for mating the female connector and the male connector. In an alternative arrangement, the female terminals, rather than the male blade terminals are staggered.

Claims

1. An electrical connection system comprising:

a female connector having a plurality of female terminals, and a male connector having a plurality of male blade terminals having projecting portions that plug into the plurality of female terminals respectively when the female connector and the male connector are moved toward each other in an engagement direction and mated,

one of the plurality of female terminals and the plurality of male blade terminals having a first population of terminals having first tips at a first relative position and a second population of terminals having second tips at a second relative position that is different than the first relative position so that the first tips and the second tips do not touch another of the plurality of female terminals and the plurality of male blade terminals at the same time thereby lowering a peak engagement force required for mating the female connector and the male connector, and

wherein the first population of terminals and the second population of terminals have identical terminals.

2. The electrical connection system of claim 1 wherein the plurality of female terminals have the first population of terminals having first tips at the first relative position and the second population of terminals having second tips at the second relative position that is different than the first relative position so that the first tips and the second tips do not touch the plurality of male blade terminals at the same time.

3. The electrical connection system of claim 1 wherein the plurality of male blade terminals have the first population of terminals having first tips at the first relative position and the second population of terminals having second tips at the second relative position that is different than the first relative position so that the first tips and the second tips do not touch the plurality of female terminals at the same time.

4. The electrical connection system of claim 1 wherein the one of the plurality of female terminals and the plurality of male blade terminals having the first population of terminals having first tips at the first relative position fully engage a mating set of another of the plurality of female terminals and the plurality of male blade terminals before the second population of terminals having second tips at the second relative position fully engage a mating set of the another of the plurality of female terminals and the plurality of male blade terminals thereby lowering the peak engagement force required for mating the female connector and the male connector.

5. The electrical connection system as defined in claim 1 wherein the peak engagement force required for mating the female connector and the male connector is reduced at least about 33%.

6. An electrical connection system comprising:

a female connector having a plurality of female terminals, and

a male connector having a plurality of male blade terminals having projecting portions that plug into the plurality of female terminals respectively when the female connector and the male connector are moved toward each other in an engagement direction and mated,

one of the plurality of female terminals and the plurality of male blade terminals having a first population of terminals having first tips at a first relative position and a second population of terminals having second tips at a second relative position that is different than the first relative position so that the first tips and the second tips do not touch another of the plurality of female terminals and the plurality of male blade terminals at the same time thereby lowering a peak engagement force required for mating the female connector and the male connector, and

wherein the peak engagement force required for mating the female connector and the male connector does not exceed about 75 newtons.
